Effect of Cold Plasma Treatment on Seed Germination and Seedling Growth of Oats Under Salt Stress
To investigate the effect of cold plasma treatment on salt tolerance of oats under salt stress,the oat seeds of Bayou 14 were used as experimental materials,and different durations(30 s,15 s×2)of 5 and 6 kV were applied to the oat seeds at differ-ent times cold plasma treatment was used to determine the germination of oat seeds,seedling growth,and physiological indica-tors under different concentrations of NaCl solution(0.5,1.0,1.5 g·L-1)stress.The results showed that cold plasma can signifi-cantly improve the hydrophilicity of oat seed coat and the water absorption rate of oat seeds,and could alleviate the effects of salt stress on oat plant height and root length.Based on the comprehensive evaluation and analysis of oat salt resistance using member-ship functions,it was found that the cold plasma treatment parameters were 5 kV,30 s,and 6 kV,15 s×2,respectively,the salt resistance of oats under stress concentration of 1.5 g·L-1 was increased.Moreover,as the stress intensity increases,the alle-viating effect of cold plasma treatment on salt stress gradually increases under 5 kV and 30 s parameters.
